QUESTION: Speed up function/Game Hours?
ANSWER: No except for the running shoes (which you get right away) and the bicycle. Storyline playtime alone will be about 35-40 hours (guesstimating). It takes me a consistent 7hr 30min, give or take a few minutes+/-, to get to Celadon City and beating Erika alone. 100% Completion will probably be about 40-50 hours.
